Synthesis and Assessment Product (SAP) 3.3: Weather and Climate Extremes in a Changing Climate. Regions of Focus: North America, Hawaii, Caribbean, and U.S. Pacific Islands

This report is one in a series of 21 Synthesis and Assessment Products (SAPs) created between 2004 and 2009 by the U.S. Climate Change Science Program, aimed at providing current assessments of climate change science in the U.S. to inform public debate, policy, and operational decisions. This SAP assesses the state of knowledge concerning changes in weather and climate extremes in North America, Hawaii, the Caribbean, and U.S. Pacific Islands.

Observed changes in North American extreme events such as hurricanes and drought, assessment of human influence for the observed changes, and likelihood that the changes will continue through the 21st century are quantified in this report.  The chapter topics include: "Why Weather and Climate Extremes Matter", "Observed Changes in Weather and Climate Extremes", "Causes of Observed Changes in Extremes and Projections of Future Changes", and "Measures To Improve Our Understanding of Weather and Climate Extremes".
